Comprehensive Product Overview: Transforming Agronomic Workflows
Cái 9LH-12 Trailed Side Delivery Rake represents the absolute apex of modern commercial forage aggregation technology. Engineered specifically for massive agricultural expanses, this industrial-grade Agricultural Rake is meticulously designed to consolidate cut forage into perfectly structured, continuous windrows perpendicular to the direction of travel. In the highly time-sensitive phase of forage harvesting, the window between cutting, drying, and baling is critical. The 9LH-12 ensures that crop is gathered rapidly and gently, producing fluffy, aerated windrows that accelerate the final evaporation of residual moisture. This optimal windrow architecture is essential for ensuring that downstream machinery, particularly a high-density round baler, can intake the biomass smoothly without blockages or mechanical hesitation.
What truly distinguishes the 9LH-12 Hay Rake in the global marketplace is its extraordinary width-to-power ratio. Spanning an astonishing 12.0 meters in operational width, this implement requires a mere 25 to 44 kW (approximately 35 to 60 horsepower) from the towing tractor. This translates to unprecedented fuel savings and reduced soil compaction, as fewer passes are required to manage vast tracts of land. Operated entirely via the tractor’s integrated hydraulic controls, a single driver can seamlessly manipulate the elevation and alignment of the 168 highly resilient rake tines. With a phenomenal leakage rate of less than 3 percent, this Farm Rake guarantees that maximum tonnage is recovered from your fields, ensuring superior economic returns on natural pastures, cultivated alfalfa fields, and high-yield gramineous forage operations.
Core Technology Quick Read

Key Features & Unrivaled Agronomic Advantages
Unmatched 12-Meter Working Span
In commercial agriculture, time is money. Covering 12 meters in a single pass fundamentally alters the mathematics of harvesting. The 9LH-12 Side Delivery Rake allows an operator to clear between 6 and 12 hectares every hour. This massive throughput ensures that cut forage is gathered quickly, minimizing exposure to unexpected rain and maximizing the utilization window of downstream baling equipment.
Sub-3% Leakage Precision
Leaving crop in the field is equivalent to leaving money on the dirt. The dense matrix of 168 highly calibrated spring tines ensures a comprehensive sweep of the terrain. Verified testing confirms a crop leakage rate of ≤ 3%. Every usable stem and leaf is recovered and integrated into the windrow, drastically improving your total tonnage yield per hectare.
Fluffy, Aerated Windrow Architecture
Compacted windrows trap moisture and invite mold. The transverse action of this Farm Rake lifts and tumbles the forage, interweaving the stems rather than crushing them together. This produces a highly porous, fluffy windrow that allows prevailing winds and solar radiation to penetrate deeply, accelerating final dry-down without damaging sensitive root structures in the soil.
Integrated Hydraulic Articulation
Operating a 12-meter implement requires intelligent control. The 9LH-12 features a heavy-duty hydraulic lifting mechanism linked directly to the tractor’s auxiliary controls. The operator can instantly hoist the 1510 kg structure to clear stumps, navigate deep irrigation ditches, and rapidly fold the massive wings into a 3.4-meter profile for safe public road transport.
Deep Engineering Dive: Structural Details & Design Philosophy
The fundamental engineering philosophy driving the 9LH-12 is “Maximum Yield Preservation through Minimal Aggression.” Traditional rotary rakes often operate with extreme centripetal force, which can violently strip high-protein leaves from the stems of legumes like alfalfa. The 9LH-12 employs a transverse, side-delivery methodology. The geometric angle of the raking frame gently rolls the biomass laterally. As the tractor advances, the crop forms a continuous rope-like structure, enveloping the fragile leaves within a protective cage of stronger stems.
Structurally, spanning 12 meters requires immense torsional rigidity. The primary chassis is fabricated from thick-walled, high-yield carbon steel tubing, continuously seam-welded to prevent flex and metal fatigue during high-speed operations across uneven terrain. The 1510 kg mass is expertly distributed across heavy-duty pneumatic flotation tires, ensuring the implement glides over the pasture without creating deep ruts or compacting the soil, thereby protecting the delicate root crowns of perennial grasses.
The primary contact points—the 168 rake tines—are forged from specialized, high-memory spring steel. These tines are engineered to flex upon encountering solid obstacles like rocks or hard earth mounds, and immediately snap back to their precise factory curvature. This resilient metallurgy ensures that the tines aggressively flick the grass upward while safely skimming just millimeters above the soil line, guaranteeing a dirt-free, premium forage harvest.
Specialized Field Application Scenarios
Deploying the correct gathering methodology based on crop and terrain profile is essential for maximizing profitability. The 9LH-12 excels in these specific, high-yield environments.
🌾 Side Delivery Rake for High-Protein Legume Harvesting
Legumes like alfalfa, clover, and vetch are highly susceptible to leaf shatter when dried. The transverse rolling action of the 9LH-12 handles these crops with exceptional care, twisting the stems around the leaves to lock in the nutrients before the baler arrives, securing premium dairy-quality hay prices.
🏞️ Agricultural Rake for Expansive Natural Prairie Grasses
When managing thousands of hectares of native grass, sheer coverage speed is the defining metric of success. Towing this massive 12-meter unit with a highly economical 40 HP tractor allows contractors to consolidate vast swaths of prairie grass rapidly, burning a fraction of the diesel required by multiple smaller rakes.
🚜 Heavy-Duty Hay Rake for High-Volume Biomass Consolidation
In high-yield environments where grass density is extreme, smaller rakes clog and leave material behind. The 168 aggressive spring tines and the wide throat of the 9LH-12 easily channel massive volumes of heavy, wet biomass into uniform, manageable windrows without overwhelming the implement’s structural limits.
Competitive Advantage Matrix: Transverse vs. Traditional
| Performance Metric | Our 9LH-12 Side Delivery Rake | Traditional High-Speed Rotary Rakes |
|---|---|---|
| Power Requirement | Ultra-Low. Achieves 12m width with only 35-60 HP. | Extremely High. A 12m rotary requires 100+ HP and heavy PTO drive. |
| Leaf Preservation (Alfalfa) | Excellent. Gentle rolling action protects dry, brittle leaves. | Poor. Violent rotary impact shatters and loses valuable protein leaves. |
| Maintenance & Complexity | Minimal. No complex gearboxes or PTO shafts to shatter. | High. Requires constant gearbox lubrication and expensive PTO repairs. |
| Windrow Quality | Rope-like, intertwined, fluffy structure. Highly aerated. | Often tightly compacted or twisted, leading to slower core drying. |
Kinematic Working Principle & Field Operation Flow
Hydraulic Deployment
The tractor operator utilizes the cab’s hydraulic remote lever to seamlessly unfold the implement from its 3.4m transport width, lowering the massive 12-meter raking structure into the optimal working position.
Forward Kinematic Engagement
Unlike a standard PTO Rake, the 9LH-12 relies on forward momentum. As the tractor advances at 5-10 km/h, the geometric angle of the raking frame engages the cut crop, initiating a sweeping, lateral movement across the field surface.
Transverse Biomass Consolidation
The 168 highly tensioned spring tines lift and pitch the grass. The crop cascades sideways from tine to tine, accumulating volume and mass as it travels the 12-meter span, gently rolling the stems and leaves together into a cohesive mass.
Perfect Windrow Formation
At the terminus of the raking frame, the accumulated forage is deposited in a perfectly uniform, continuous windrow. The size and density of this windrow can be expertly manipulated by the operator adjusting the tractor speed based on field yield.
Drivetrain & Fleet Selection Guide
Procuring the 9LH-12 requires understanding how it will interact with your existing fleet. Use this rapid selection checklist to ensure perfect operational harmony and maximum field efficiency.
| Operational Requirement | Minimum Fleet Specification | Agronomic Justification |
|---|---|---|
| Tractor Horsepower | 35 – 60 HP (25 – 44 kW) | The lack of a rotary PTO drive means power is only needed to pull the 1510kg mass and power the hydraulic lift. |
| Hydraulic Capability | 1x Rear Auxiliary Remote Valve | Mandatory for articulating the heavy structure from transport to working mode, and for instantly clearing field obstacles. |
| Field Topography | Flat to Gently Rolling Terrain | A 12-meter rigid span performs best on relatively level ground to ensure all 168 tines maintain consistent ground contact. |
| Target Crop Profile | Alfalfa, Native Grass, High-Yield Hay | The transverse rolling action is specifically designed to protect delicate leaves and consolidate massive volumes without clogging. |
Global Engineering Field Notes & Verified Case Studies
[Texas, USA] Extreme Working Condition Practical Research
Client: Mega-Scale Commercial Alfalfa Exporter. Objective: Preserving RFV (Relative Feed Value) in brutal 42°C dry heat.
“In our dry heat, alfalfa leaves become brittle almost instantly. Using high-speed rotary rakes was turning our profits to dust. The gentle, lateral rolling action of the 9LH-12 Side Delivery Rake wraps the stems around the leaves, locking the protein inside the windrow. Our buyers have noted a significant increase in leaf retention.”
[Queensland, Australia] Off-Road Terrain Adaptation Guide
Client: Massive Outback Cattle Station. Objective: Harvesting sparse native grasses over immense, unending acreage efficiently.
“When your paddocks stretch for horizons, width is everything. Pulling a 12-meter rake with an old 45 HP tractor seems impossible, but because it’s ground-driven and trailed, the tractor hardly breaks a sweat. We are clearing 10 hectares an hour, and the fuel savings alone paid for the machine in the first season.”
[Mato Grosso, Brazil] Local Industry Application Cases
Client: Heavy-Yield Tropical Forage Contractor. Objective: Consolidating massive volumes of thick, wet tropical grass rapidly.
“Tropical grasses can yield an absurd tonnage per hectare. Smaller rakes just clog and drag. The 168 heavy-duty tines on the 9LH-12 chew through the thickest biomass we can throw at it. It creates a windrow the size of a car, perfectly aerated so the tropical sun can dry the core out before baling.”
[Bavaria, Germany] Precision Ash-Reduction Agronomy
Client: Intensive Rotational Grazing Dairy. Objective: Minimizing soil (ash) contamination in fermented ryegrass silage.
“Silage quality is ruined by dirt. The heavy pneumatic tires on this implement act as a perfect depth gauge. By finely adjusting the drawbar, the tines flick the grass up without ever scratching the soil. Our lab tests show a 40% reduction in ash content since adopting this specific model.”
[Pampas, Argentina] Heavy-Yield Pasture Windrowing
Client: Broadacre Mixed Farming Enterprise. Objective: Reducing maintenance downtime associated with complex PTO machinery.
“We used to run massive rotary rakes, but blowing a gearbox in the middle of harvest cost us days of downtime. The 9LH-12 has virtually no complex moving drivetrain parts. It’s structural steel, hydraulic rams, and spring tines. It simply does not break down. Reliability is off the charts.”
B2B Client Frequently Asked Questions (FAQ)
1. How is a 12-meter wide machine shipped internationally?
To maximize freight economics, the 9LH-12 is shipped in an SKD (Semi-Knocked Down) configuration. The main chassis sections, drawbar, and wheel assemblies are flat-packed. A standard 40ft High Cube container can efficiently house multiple units, radically reducing your landed cost per implement.
2. Does this machine require a PTO shaft to operate?
No. Unlike a dedicated PTO Rake, the gathering action of the 9LH-12 is driven by the forward motion of the tractor interacting with the geometric angle of the frame. The only connection required to the tractor is the drawbar pin and a single hydraulic hose for the lifting mechanism.
3. What happens if the rake tines strike a hidden boulder?
The 168 tines are forged from specialized high-memory spring steel. They are designed to flex severely backward to absorb the kinetic impact of solid obstacles and immediately snap back to their original curvature without permanent deformation or snapping.
4. How difficult is it to transition the machine for road transport?
It is incredibly efficient. Using the tractor’s hydraulic remote, the operator actuates the massive lift cylinders, raising the wide frame and pivoting it into a trailing position. The working width of 12000mm is rapidly condensed into a road-safe transport width of just 3400mm.
5. Can the operator adjust the size and volume of the windrow?
Yes. Windrow architecture is entirely operator-controlled. By adjusting the forward speed of the tractor (between 5 and 10 km/h) relative to the crop yield density, the operator can create a tighter, denser windrow or a wider, fluffier swath optimized for their specific baler’s pickup width.
6. Is a 35 HP tractor truly capable of pulling a 12-meter, 1500kg implement?
Absolutely. Because there is no mechanical PTO drag powering a heavy gearbox, the tractor is merely towing a rolling chassis. On flat, firm pastureland, 35 HP provides ample torque. However, if operating on steep inclines or deep mud, scaling up to a 60 HP tractor is recommended to maintain traction.
7. How do I order replacement spring tines or hydraulic seals?
As a fully integrated OEM manufacturer, we stock every consumable and structural component. You can order replacement tines, hydraulic rams, agricultural gearboxes, PTO shafts (for other equipment), and hardware kits directly through our B2B sales portal for rapid global dispatch.
8. Does the 9LH-12 perform well on heavily lodged (flattened) crops?
Yes. Because the 168 tines aggressively flick upward, they are highly effective at getting under crops that have been beaten down by rain or wind, lifting the matted biomass and aerating it into a dryable windrow.
Critical Field Calibration & Engineering Precautions
To guarantee a sub-3% leakage rate and protect your capital investment, adhere strictly to these operational protocols:
- Hydraulic System Bleeding: Upon initial commissioning or after prolonged storage, fully cycle the hydraulic lift cylinder 5 to 6 times. This bleeds trapped atmospheric air from the lines, preventing dangerous, spongy drops of the 1510 kg frame during transport.
- Tine Height Calibration: The spring tines must NEVER drag continuously in the dirt. Adjust the heavy-duty drawbar leveling screw so the lowest point of the tines hovers approximately 15-25mm above the soil line. This ensures clean forage and prevents premature tine snapping.
- Cornering Dynamics: Because of the extreme 12-meter working width, operators must execute wide, sweeping turns at the headlands. Sharp, acute turns while engaged will cause the outer raking frame to swing violently, potentially damaging the chassis or tearing up the pasture turf.
Macro Economic Trends & ROI Analysis
The trajectory of global commercial agriculture is sharply focused on consolidation and cost reduction. The era of running multiple small tractors with 3-meter rakes is economically obsolete due to soaring diesel prices and chronic labor shortages. The modern imperative is “Maximum Width, Minimum Input.” The 9LH-12 Side Delivery Rake is the physical manifestation of this economic trend, replacing three separate smaller machines and three operators with a single, highly efficient 12-meter pass.
Return on Investment (ROI) Economics: The mathematics of the 9LH-12 are staggering. By clearing up to 12 hectares per hour using a low-consumption 40 HP tractor, fuel expenditure per hectare drops by an estimated 60% compared to high-RPM rotary setups. Furthermore, the total lack of complex gearboxes eliminates the expensive seasonal overhauls associated with PTO-driven machinery. For a commercial hay operation managing 500+ hectares, the combined savings in diesel, labor hours, and maintenance parts routinely amortize the entire capital cost of the 9LH-12 within the first half of the harvesting season, while the gentler handling produces a higher-protein, premium-priced bale.
